The super 10 is an ok Trans i think , i never tore one oup and i tried believe me. the only thing i had wrong with it was in cold mornings the splitter was a little slow, other than that an excelent drag race tranny. It worked great with the jake brake for down shifting.

I was slways told to fire-wall macks till they hit on all 6. I drove an R model that had so much fuel turned to it you couldnt touch the pedal at all, it would make it worse. Make sure the ether u buy is for diesel engines. I think they have oil additves in some ethers specifically for diesel engines.

HEY GUYS I GOT THE BIBLE OUT NOW.HOE TO IDETIFY YOUR ENGINE SERIAL # IS
E = MACK TURBO CHARGED DIESEL ENGINE
M = MAXIDYNE ENGINE (HIGH TROQUE RISE ENGINE)
C = CALIFORNIA CERTIFIED
6 = FIRST DIGIT INDICATES CUBIC INCH DISPLACEMENT ( 672 I.E.)
NEXT THREE NUMBERS MEAN PEAK GROSS HORSEPOWER (BHP)
THE LAST 2 LETTERS COULD BE AN L OR AN R
L = LOW SPEED MAXIDYNE
R = REDUCED ENGINE SPEED

THE 6 CYLINDER MACKS WERE OF THE SAME BLOCK WITH THE DIFFERENCE OF A COUPLE OF CUBES. THE ONLY THINGS THAT CHANGED FOR MORE HORSE POWER WERE THE TURBO, INJECTORS, PUMP, INTERCOOLER. MY DADS WORKED ON THEM FOR 30 YEARS HE SAID THAT THOSE FEW CHANGES IN CUBES DIDNT AMOUNT TO A HILL OF BEANS. MACK WAS ALWAYS KNOWN FOR BAD CAMSHAFTS( DYNATARDS) THATS WHY JACOBS BRAKES WERENT TO POPULAR. I THINK THE 4V HEAD WASNT MADE TILL 88. I GOT AN 87 WITH 2V HEADS AND HAD AN 88 WITH 4V HEAD AND TRENTS RIGHT THE BEST WAY TO TELL IF ITS 4V IS TO SEE IF THE INJECTOR COME IN THE SIDE OF THE HEAD (PASSENGER).
HOPE THIS HELPS JOE

I would recomend a detachable front clip for anything u put a 3208 in. They dont call them scatterpillars for nothin.lol. Not to be steppin on toes but thats the boat anchor cat should have never made.

Imagine pulling into the local truck stop and tellin the u got a low tire.
-
Howd yu guys like to change all those tires? lol.

my grandfather had a 460 which is the same as the 427 or 454 except for computer and the fan. But the local dealer did tell us that they changed a diode in the air intake sensor to make the truck think that it was cold outside all the time. by this i mean when in the winter time the air is denser and more is takin in the intake thus more fuel added too (via) the computer. its kind of like taking the puff-elliminator off the e-6 300's. better take off and harder pulling at low rpm's it will smoke too.

MY DAD HAS AN R MODEL WITH THE STACK OUT THE HOOD, HE PUT THAT STACK THERE FOR TRUCK PULLIN. IT ALSO HAS ONE OF THE RAREST MACK TRANSMISSIONS TOO. IT HAS REV. AND 1-5 ON ONE STICK AND ON THE OTHER STICK IT HAS DIRECT OND OVERDRIVE .
HE SAID IT IS THE HIGHEST GEARED TRANS EVER MADE .60 IS THE FINAL DRIVE. THE TRUCK RUNS 73 MPH @ 2500 RPM THEN U PUT IN OVERDRIVE AND IT DROPS BACK TO 1200 RPM THIS OLD MACK HAS BLOWN MORE PETERBILTS TO THE WEEDS THAN I CAN COUNT.LOL. ITS A BLAST TO DRIVE. WHEN U GET THAT THING ON THE ROAD THE C.B. SOUNDS LIKE YOUR AT AN AUCTION. JOE
ILL GET SOME PICS FOR U GUYS.

HEY TIM
DOESNT YOUR PYRO GET HOT BEFORE THE WATER TEMP? THIS DOESNT MAKE SENSE TO ME . PULLING A HILL THE PYRO SHOULD GET HOT FIRST THEN THE WATER TEMP. UNLESS THERE IS SOME AIR FLOW RESTICTION TO THE RADIATOR. JOE

I talked to Howard at goodys 2 days ago he said that they have 1 v8 out of an 88 superliner. He told me 5500 minus 2000 for exchange.he didnt give me milage or what style of fuel pump it had, thats all i asked
-
The 237 motor does not have a tip fan. Also the pump should be different. the difference in the pumps are easy to tell, the 237 pump has a sloped top on the govoner(where the 6 bolts hold the cap on to keep people out of the fuel adjustment). the 300 motors have a flat top on the govoner. thats how u tell whether its a 237 or a 300.

Those individual valve covers make it look like it has individul heads ( just like those KT cummins motors).
